Module Installation
Compact I/O is suitable for use in an industrial environment when installed in
accordance with these instructions. Specifically, this equipment is intended for
use in clean, dry environments (Pollution degree 21) and to circuits not exceeding
Over Voltage Category II2 (IEC 60664-1).3
Prevent Electrostatic Discharge
!
ATTENTION: Electrostatic discharge can damage integrated
circuits or semiconductors if you touch bus connector pins.
Follow these guidelines when you handle the module:
• Touch a grounded object to discharge static potential.
• Wear an approved wrist-strap grounding device.
• Do not touch the bus connector or connector pins.
• Do not touch circuit components inside the module.
• If available, use a static-safe work station.
• When not in use, keep the module in its static-shield box.
Remove Power
!
ATTENTION: Remove power before removing or inserting
this module. When you remove or insert a module with power
applied, an electrical arc may occur. An electrical arc can cause
personal injury or property damage by:
• sending an erroneous signal to your system’s field devices,
causing unintended machine motion
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create
electrical resistance.
1.Pollution Degree 2 is an environment where, normally, only non-conductive pollution
occurs except that occasionally a temporary conductivity caused by condensation shall
be expected.
2.Over Voltage Category II is the load level section of the electrical distribution system. At
this level transient voltages are controlled and do not exceed the impulse voltage
capability of the product’s insulation.
3.Pollution Degree 2 and Over Voltage Category II are International Electrotechnical
Commission (IEC) designations.

1. Disconnect power.
2. Check that the bus lever of the module to be installed is in the unlocked
(fully right) position.
3. Use the upper and lower tongue-and-groove slots (1) to secure the modules
together (or to a controller).
4. Move the module back along the tongue-and-groove slots until the bus
connectors (2) line up with each other.
5. Push the bus lever back slightly to clear the positioning tab (3). Use your
fingers or a small screw driver.
6. To allow communication between the controller and module, move the bus
lever fully to the left (4) until it clicks. Ensure it is locked firmly in place.
!
ATTENTION: When attaching I/O modules, it is very
important that the bus connectors are securely locked
together to ensure proper electrical connection.
7. Attach an end cap terminator (5) to the last module in the system by using
the tongue-and-groove slots as before.
8. Lock the end cap bus terminator (6).
IMPORTANT: A 1769-ECR or 1769-ECL right or left end cap must be used to
terminate the end of the serial communication bus.

Compact™ 240V ac Input Module
Panel Mounting Procedure Using Modules as a Template
The following procedure allows you to use the assembled modules as a template
for drilling holes in the panel. If you have sophisticated panel mounting
equipment, you can use the dimensional template provided on page 5. Due to
module mounting hole tolerance, it is important to follow these procedures:
1. On a clean work surface, assemble no more than three modules.
2. Using the assembled modules as a template, carefully mark the center of all
module-mounting holes on the panel.
3. Return the assembled modules to the clean work surface, including any
previously mounted modules.
4. Drill and tap the mounting holes for the recommended M4 or #8 screw.
5. Place the modules back on the panel, and check for proper hole alignment.
6. Attach the modules to the panel using the mounting screws.
Note: If mounting more modules, mount only the last one of this group
and put the others aside. This reduces remounting time during
drilling and tapping of the next group.
7. Repeat steps 1 to 6 for any remaining modules.
DIN Rail Mounting
The module can be mounted using the following DIN rails: 35 x 7.5 mm (EN 50
022 - 35 x 7.5) or 35 x 15 mm (EN 50 022 - 35 x 15).
Before mounting the module on a DIN rail, close the DIN rail latches. Press the
DIN rail mounting area of the module against the DIN rail. The latches will
momentarily open and lock into place.

Replacing a Single Module within a System
The module can be replaced while the system is mounted to a panel (or DIN rail).
1. Remove power. See important note on page 3.
2. On the module to be removed, remove the upper and lower mounting
screws from the module (or open the DIN latches using a flat-blade or
phillips style screw driver).
3. Move the bus lever to the right to disconnect (unlock) the bus.
4. On the right-side adjacent module, move its bus lever to the right (unlock)
to disconnect it from the module to be removed.
5. Gently slide the disconnected module forward. If you feel excessive
resistance, check that the module has been disconnected from the bus, and
that both mounting screws have been removed (or DIN latches opened).
Note: It may be necessary to rock the module slightly from front to back
to remove it, or, in a panel-mounted system, to loosen the screws of
adjacent modules.
6. Before installing the replacement module, be sure that the bus lever on the
module to be installed, and on the right-side adjacent module are in the
unlocked (fully right) position.
7. Slide the replacement module into the open slot.
8. Connect the modules together by locking (fully left) the bus levers on the
replacement module and the right-side adjacent module.
9. Replace the mounting screws (or snap the module onto the DIN rail).
Field Wiring Connections
Grounding the Module
This product is intended to be mounted to a well-grounded mounting surface
such as a metal panel. Additional grounding connections from the module’s
mounting tabs or DIN rail (if used), are not required unless the mounting surface
cannot be grounded. Refer to Industrial Automation Wiring and Grounding
Guidelines, Allen-Bradley publication 1770-4.1, for additional information.

A removable, write-on label is provided with the module. Remove the label from
the door, mark the identification of each terminal with permanent ink, and slide
the label back into the door. Your markings (ID tag) will be visible when the
module door is closed.
1.A current limiting resistor can be used to limit inrush current; however, the operating
characteristics of the ac input circuit will be affected. If a 15K W resistor is placed in series
with the input, the inrush current is reduced to 35 mA. In this configuration the minimum
on-state voltage increases to 176V ac.
Before adding the resistor in a hazardous environment, be sure to consider the operating
temperature of the resistor and the temperature limits of the environment. The operating
temperature of the resistor must remain below the temperature limit of the environment.

Removing the Finger-Safe Terminal Block
To remove the terminal block, loosen the upper and lower retaining screws. The
terminal block will back away from the module as you remove the screws. When
replacing the terminal block, torque the retaining screws to 0.46 Nm (4.1 in-lbs).
Wiring the Finger-Safe Terminal Block
When wiring the terminal block, keep the finger-safe cover in place.
1. Loosen the terminal screws to be wired.
2. Route the wire under the terminal pressure plate. You can use the bare wire
or a spade lug. The terminals will accept a 6.35 mm (0.25 in.) spade lug.
Note: The terminal screws are non-captive. Therefore, it is possible to use a ring
lug [maximum 1/4” o.d. with a 0.139” minimum i.d. (M3.5)} with the
module.
3. Tighten the terminal screw making sure the pressure plate secures the wire.
Recommended torque when tightening terminal screws is 0.68 Nm (6 inlbs).
Note: If you need to remove the finger-safe cover, insert a screw driver into one
of the square, wiring holes and gently pry the cover off. If you wire the
terminal block with the finger-safe cover removed, you will not be able to
put it back on the terminal block because the wires will be in the way.
